SOLDER lNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 248,161, dated October11, 1881,

Application filed Angnst .19, 1881. (No model.)

To all whom it may concern Be it known that I, JOHN GnAvns, of the cityof Brooklyn, in the county of Kings and State of New York, have inventedcertain new and useful Improvements in Soldering-M11 subsequently, itnecessary, past and through water baths, whereby the soldered scams oredges are cooled, the cans being turned meanwhile to properly presentsuccessively the seamsto be soldered.

An important object of this invention is to provide in a simple andeffective manner for turning the can-holders in which the cans are held,after the four seams at one end of the cans are. soldered, so as toreverse the can end for end to bring the opposite end of the can inposition to have its four seams'soldered.

The invention consists in the combination, in a soldering-machine, of astationary track, a carriage rnnnin g thereon, a can-carrier having aspindle or shaft j ournaled in said carriage, so that it is free torotate therein, and a canholder supported upon trunnions in saidcarrier, and adapted to be tilted or turned in a plane parallel with theaxis of rotation of said carrier, to bring the two ends of the can intoposition to be passed through the acid and The invention also consistsin a novel com-3 bination of mechanism for turning thecan-carrierspindle or shaft and carrier in the carriage while the can is passingfrom one vessel or bath to another, and for locking the can-car rier tothe carriage, so thatit cannot turn while the can is passing over eachvessel or bath, and unlocking the carrier from the carriage when it isto be turnedtbetween the vessels or baths.

The invention also consists in the combination, with the can-carrier, ofa pusher-rod fitting loosely within the carrier spindle or shaft, and astationary cam past which the carrier is moved, and by which thepusher-rod is moved longitudinally-to automatically eject thecan fromthe holder.

In the accompanying drawings, Figure 1 represents a plan of a portion ofa machine embodying my invention. Fig. 2 represents a vertical sectionthereof, the can in both figures being represented as passing through anacid vessel or bath; and Figs. 3 and 4 represent a similar plan andsection, showing the position of the parts while reversing the can endfor end.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the frame-work or bed-plate ot' the machine, hererepresented as of circular form, and B, G, and D designate,respectively, acid, solder, and water vessels or baths, arranged in acircular series around the bedplate A.

Although the water vessels or baths might be dispensed with they arepreferably employed.

At each'end of the cans are four seams, and

hence for soldering the two ends while in the machine eight vessels orbaths of each kind are necessary, and they are arranged in the orderabove named. As here represented the several vessels or baths are shownupon an enlarged scale for the sake of clearness, ,and twenty-four couldnot be arranged in the-cirole; but in practice they would be smaller andplaced nearer together if twenty-four are used.

E designates carriages, of which there may be as many as there arevessels or baths, so that twenty-four cans may be in themachine at onetime. The carriages are provided with wheels a, which run upon lowerstationary tracks, I), on the bed-plate A, and they are likewiseprovided with wheels a, which run upon an upper stationary track, 2),whereby the carriages are held against tilting outward. The severalcarriages are all connected by means of a chain, c, to which they areattached at proper distances apart, and motion is imparted to them bymeans of a sprocket-wheel, F, which is secured upon a shaft, F, arrangedradially to the bed-plate A in bearings F and having 10 all rotarymotion imparted to it by a bevel-pinion, F and wheel I from a verticalshaft, F as clearly seen in Fig. 2, and in dotted outline in Fig. 1.Each carriage, E, is constructed with a long bearing, E, arranged at anincline, and in said bearing is mounted a shaft or spindle, G, at thelower end of which is secured or formed a carrier, G, comprising arms,between which is arranged a can-holder, H. The spindlc or shaft G andcarrier G are formed in one piece or rigidly connected, so that theyrotate together, and the spindle or shaft is hollow or tubular, for apurpose hereinafter explained,

The can-holder H consists of a tubular rectangular band or socket, intowhich the cans may be inserted, and which is of a size to fit the canssufficiently closeto retain them against movement therein. Said holderis mounted upon trnnnions d, which are journaled in the arms of thecan-carrier G, and the holder may be turned upon its trunnions in aplaneparallel with the carrier spindle or shaft G, to reverse the canend for end, by means of a bevelwl1eel,e, which is fixed upon one of thetrunnions, and with which engages a similarbevelwheel, e, fixed upon asmall shaft. 0 arranged at the side of the carrier G, and having fixedupon it a spur-pinion, 6 which is turned as hereinafter described.

I designates a spur-gear wheel, secured upon the spindle or shaft G ofthe carrier G, so as to impart rotary motion thereto and move the samelongitudinally. Upon the wheel I is an inclined or taper flange, f, andupon the bedplate A is a track or way, g, upon which the said flangerides as the carriage is moved along, and upon each wheel is a pin orprojection, 10-, which, when the wheel is in the position shown in Fig.2, enters one or the other of four holes, 71, in the bearing E, and thusholds the cancarrier G and the can J against turning.

In order to enable the can to pass over the the edges of the vessels orbaths in passing from one to another it is necessary to slightly raisethe spindle or shaft G and carrier G, and at the same time it isnecessary to prevent the spindle or shaft and carrier from turning. Toelfect this result I form in the track or way 9 between each acid andsolder vessel or bath and between each solder and water vessel or bath aslight upward projection or cam. g, along which the flangef of the wheelI rides, and by which the spindle or shaft G, the carrier G, and the camJ are raised sufficiently to enable the lower edge of the can to clearthe edges of the baths, but not suiiiciently to remove the pin it fromits hole It and permit the can to turn. As soon as the wheel I passesthe projecting cam g the carrier G and can move downward by gravity andthe edge of the can is lowered into the contents of the bath.

Between each water vessel or bath D and its adjacent acid bath, whileone end of the can is being soldered, it is necessary to turn thecarrier G, with its spindle or shaft G, a quarter of a turn, so as topresent a new edge of the can to be soldered. To efi'cct this 1 form inthe track g between each water vessel or bath and its adjacent acidvessel or bath a cam, of greater projection than the cams g, and I alsoform in each cam g spur-gear teeth or stationary racks, with which theteeth of the pinion or wheel I may engage. When the flange f of thewheel I rides up on the cam it raises the wheel I sufliciently to removethe pin it from its hole h, and the continued operation causes thegear-wheel I to engage with the gear-teeth or stationary rack g, andthus turn the spindle or shaft G and the carrier G and can to present anew edge to be soldered. After the wheel I passes the cam g the spindleor shaft and carrier descend and the pin it enters another hole h in thebearing E, and thus locks the carrier against rotation.

Once during the circuit of the can in themachine it is necessary to turnthe can-holder H upouits trunnions d to reverse the can end for end, andthis is done while the can is passing from one water vessel or bath toits adjacent acid vcssel or bath.

Opposite one of the cams g of lesser pro jection is a stationary raclnj,(seen in Figs. 3 and 4,) and as the can-carrier G is moved along, thespur-wheel upon the shaft 0 comes into engagement with said stationaryrack, and by its rotation turns the can-holder and can end for end.

In order to hold the can-holder immovably in the carrier after reversalI may employ a pin or dent, 7c, fixed upon a spring, whereby it is madeto engage with a depression in the canholder sufficiently to offer aslight obstacle to the turning of the holder, though not to prevent itsbeing turned by force.

As before stated, the shaft or spindle G of the can-carrier G istubular, and therein is arranged a pusher-rod, K, which is provided atits lower end with a plate, K, and atits upper end with a head, I. Whennot otherwise actuated, said pusher-rod is maintained in an elevatedposition by a spring, rearranged between its head land the end of theshaft or spindle G. When the can has had all its seams soldered, thecarrier is brougl'it opposite astationary cam, L, (shown in Figs. 1 and2,) and the end of the pusher-rod K bears against this cam, and is by itforced in sufficiently to act upon the can J and force it from theholder H, thus ejecting the cans automatically at the proper time. Asthe can-holders are emptied, one by one, they are filled with cans to besoldered, and the operation of the machine is continuous. As hererepresented, the carriages E, and also the cams g g in the track or way9, are too large, and so far apart as to prevent the proper number ofeach from being placed in the circle. This is, however, simply to enablethe machine to be more clearly illustrated, and I would here remark thatwhere the eight seams at the two ends of a can are to be soldered at oneoperation twenty'four vessels or IIO baths are necessary, and the trackor way 9 should have six of the cams g of great projec-.

tion provided with teeth, and eighteen of the lesser cams, g.

By my invention I provide a simple machine in which the cans after beingplaced in the machine are soldered at both ends and dischargedautomatically.

What I claim as my invention, and desire to secure by Letters Patent, is
